For those who have problem with emails: If your iphone have a jailbreak you can use BTNotificationEnabler from Cydia.

Id like to say that this indeed does work. Emails still show up as texts on the idrive, but the work around of changing the number of unread items from 5 to 10 or vice versa each time you get in the car does not have to be done now. Nothing has to be done, it works seamless and works with all different types of notifications. Kudos to whomever developed this neat application!!
